E-Mail-Management und seine systemtechnische Unterstützung in der Hotellerie

Für Beherbergungsbetriebe ist E-Mail ein wichtiges Kommunikationsmedium im elektronischen Kanal geworden. Die Bedeutung von E-Mails für die Kundenkommunikation zieht die Forderung nach einem systematischen und professionellen E-Mail-Management nach sich. Derzeit tut sich die Mehrzahl der Betriebe schwer, den damit verbundenen hohen Anspruch einzulösen. Zwar werden grundlegende Anforderungen bezüglich des Antwortverhaltens mehrheitlich erfüllt, jedoch kann die Qualität der Antworten hinsichtlich Inhalt und Form in vielen Fällen nur bedingt überzeugen. Angesichts dieser Problemlage mag es überraschen, dass die Unterstützung durch Informationssysteme in diesem Zusammenhang bis jetzt keine besondere Rolle spielt. In vielen Fällen erfolgt das E-Mail-Management mithilfe des generellen E-Mail-Programms Outlook von Microsoft. Die häufig eingesetzten branchenspezifischen Property-Management-Systeme (PMS) decken die geforderten Funktionalitäten bestenfalls teilweise ab. Spezifische Informationssysteme zur Unterstützung des E-Mail-Managements - sogenannte E-Mail-Response-Management-Systeme (ERMS) - könnten bei der Entschärfung der manifesten Probleme sehr nützlich sein. Die systemtechnische Unterstützung durch ERMS wird von Praktikern jedoch mit einiger Skepsis bedacht und nur teilweise als praktisch umsetzbar und nützlich eingeschätzt.

Understanding virtual experience and telepresence - a review and synthesis of literature

To enable buyers to be better informed before purchasing, products and services can be virtually experienced on the internet. Research into virtual experience (VE) and the related construct of telepresence (TP) as means of online marketing has made great progress in recent years. However, there is still disagreement in the literature concerning the exact understanding of these terms. In this study, the two terms are analyzed by means of a systematically executed literature review, differentiated from one another, and their understandings explained. This study is to our knowledge the first to compare the concepts of VE and TP in a systematic way. The analysis shows that TP is regarded as the feeling of presence conveyed by a communication medium. VE, on the other hand, is to be defined as an active state of a consumer through the use of computer-based presentation formats, and constituting a subtype of TP. These findings are intended to help VE and TP become more uniformly understood and make it easier to compare the results of future studies. Finally, from the literature review, it is possible to derive focal points for research in future studies.

F. + H. Engel AG: Erfolg mit releasefähiger Standard-Software

Die Firma F. + H. Engel AG ist ein Bieler Familienunternehmen, das an fünf Standorten tätig ist und die Geschäftsbereiche Stahl, Haustechnik und Eisenwaren abdeckt. Seit über 15 Jahren setzt ENGEL für die Unterstützung ihrer Handelsprozesse die Standardsoftware OpaccOne ein. Dabei orientiert sich das Unternehmen an den durch die Software gegebenen Möglichkeiten, um eine möglichst sichere, stabile und langfristig tragfähige Lösung sicher zu stellen. Dank der Releasefähigkeit der gewählten Standard-Business-Software profitierte Engel ohne grössere Umstellungen von deren laufend erweiterten Fähigkeiten in Bezug auf Funktionalität, Technologie, Anpassungs- und Erweiterungsmöglichkeiten. Dadurch konnte sich ENGEL über die Jahre mit dieser Software stetig weiterentwickeln und auch neue Anforderungen abdecken. Problematisch erwies sich die durch die Einführung eines Webshops deutlich höhere Anforderung an Umfang und Qualität der Produktstammdaten für das umfangreiche Sortiment. Der Aufwand für deren Pflege konnte von ENGEL auf die Dauer nicht geleistet werden. Deshalb entschied man sich für eine zweigleisige Strategie, indem für einen Teil des Sortiments auf die Dienstleistungen eines externen Inhaltsanbieters zurückgegriffen wird

Effektives Customer Relationship Management durch Intermediation

Bestehende Modelle im Customer Relationship Management (CRM) weisen diverse Schwachstellen auf. Erstens sind viele Kunden durch die große zu verarbeitende Informationsmenge überfordert, zweitens gelingt es vielen Anbietern nicht, die Konsistenz und Relevanz der gesammelten Kundendaten zu gewährleisten, und drittens bringen Kunden den Anbietern nicht das Vertrauen entgegen, das für eine umfassendere Offenlegung von Kundendaten erforderlich wäre. Durch die Einschaltung eines Intermediärs können diese Schwachstellen gemildert werden. Zusätzlich bietet die Intermediation die Möglichkeit, Transaktionskosten zu senken, die Macht der Kunden zu bündeln und die Beziehungen zu Kunden zu intensivieren. Ermöglicht wird dies durch die engere Verknüpfung der Kommunikations- und der Einkaufsfunktionalitäten des Internets. Als Erfolgsfaktoren gilt es, die kritische Masse und das erforderliche Vertrauen zu erreichen sowie einen wesentlichen Beitrag zur Wertschöpfung zu leisten.

Quality of feedback to e-mail requests - an explorative study in alpine tourism destinations

The central aim of our project is to explore the handling of e-mail request from customers by tourist organisations and to explain the perceived behaviour. For this purpose, we designed a qualitative empirical study which consists basically of two stages. The first stage consists of a black-box test where we employ the setting of a qualitative experiment to measure the behaviour of the organisation to an e-mail request. The second stage comprises a with-box test where we want to look into the tourist organizations and analyse the relevant information processes. This study should give as some insight in the internal processing of e-mail requests and thus should help to explain the reactions that we registered.

Repeatedly experiencing information overload in a product customization: a case of sequential overchoice

The present study demonstrates how consumers can suffer from sequential overchoice. Customizing a tailor-made suit from combined-attribute choices (e.g., deciding on color and fabric in combination) leads to less satisfaction and less additional consumption than customizing it from single-attribute choices (e.g., deciding on color, then on fabric). The effect is mediated by information overload and moderated by consideration set size.

Balance theory in eWOM: Even if you red-flag this product, I like it, as I dislike you

In eWOM the relationship between the consumer and the reviewer is weak. Still, the present study argues that social information, for example the reviewer`s user picture, influences the product evaluation. By applying balance theory we predict that the evaluation of the recommended product is a function of the induced attitude towards the reviewer and the valence of the review. By utilizing either positive or negative user pictures and either positive or negative reviews, we confirmed the hypothesized interaction. Consumers rated a negatively reviewed product more favorable when the reviewer used a negative user picture, compared to a positive user picture.

Assimilation and contrast in web product reviews: devaluing the recommendation of a proficient but dissimilar reviewer

When viewing web-consumer reviews consumers encounter the reviewers in an anonymous environment. Although their interactions are only virtual they still exchange social information, e.g. often reviewers refer to their proficiency or consumption motives within the review texts. Do these social information harm the viewers’ perception of the recommended products? The present study addresses this question by applying the paradigm of social comparison (Mussweiler, 2003) to web-consumer reviews. In a laboratory experiment with a student sample (n = 120) we manipulated the perceived similarity between reviewer and viewer and the perceived proficiency of the reviewer. A measurement of achievement goals (Elliott & McGregor, 2001) and average number of hours of study prior to the experiment allowed to introduce the reviewer as high [low] in proficiency and similar [dissimilar] in achievement goals. As predicted, the viewer’s evaluation of the recommended products differed as a function of this social information. Contrasting with the reviewer led to devaluing the products recommended by a proficient but dissimilar reviewer. However, against our prediction social comparison with the reviewer did not affect the viewer`s self-evaluation. Whether social information in web-product reviews affects the viewer`s self-evaluation and induces both social comparison processes remains an open question. Future studies aim to address this by manipulating the informational focus of the viewer, rather than the perceived similarity between viewer and reviewer. So far, the present study extends the application of social comparison to consumption environments and contributes to the understanding of the virtual social identity.

Scheduling of continuous and discontinuous material flows with intermediate storage restrictions

This paper deals with scheduling batch (i.e., discontinuous), continuous, and semicontinuous production in process industries (e.g., chemical, pharmaceutical, or metal casting industries) where intermediate storage facilities and renewable resources (processing units and manpower) of limited capacity have to be observed. First, different storage configurations typical of process industries are discussed. Second, a basic scheduling problem covering the three above production modes is presented. Third, (exact and truncated) branch-and-bound methods for the basic scheduling problem and the special case of batch scheduling are proposed and subjected to an experimental performance analysis. The solution approach presented is flexible and in principle simple, and it can (approximately) solve relatively large problem instances with sufficient accuracy.

Scheduling the factory pick-up of new cars

Car manufacturers increasingly offer delivery programs for the factory pick-up of new cars. Such a program consists of a broad range of event-marketing activities. In this paper we investigate the problem of scheduling the delivery program activities of one day such that the sum of the customers’ waiting times is minimized. We show how to model this problem as a resource-constrained project scheduling problem with nonregular objective function, and we present a relaxation-based beam-search solution heuristic. The relaxations are solved by exploiting a duality relationship between temporal scheduling and min-cost network flow problems. This approach has been developed in cooperation with a German automaker. The performance of the heuristic has been evaluated based on practical and randomly generated test instances.

Scheduling the production of rolling ingots: Industrial context, model, and solution method

We study a real-world scheduling problem arising in the context of a rolling ingots production. First we review the production process and discuss peculiarities that have to be observed when scheduling a given set of production orders on the production facilities. We then show how to model this scheduling problem using prescribed time lags between operations, different kinds of resources, and sequence-dependent changeovers. A branch-and-bound solution procedure is presented in the second part. The basic principle is to relax the resource constraints by assuming infinite resource availability. Resulting resource conflicts are then stepwise resolved by introducing precedence relationships among operations competing for the same resources. The algorithm has been implemented as a beam search heuristic enumerating alternative sets of precedence relationships.
